10 Claims.

The invention relates to a washing machine and more especially to dish washing machines. The primary object of the invention. is the provision of a machine of this character, wherein the construction thereof adapts the samefor family use or for domestic purposes in washing dishes, pots, pans, skillets, bottles, jars and the like, thereby eliminating hand labor for this purpose, being automatic in the working.

Another object of the invention is the provision of a machine of this character, wherein through centrifugal action water under pressure is forced stacked during the process of the washing operation of the machine, there being no liability of breakage in that the contents of the machine are held fixed so that they cannot work against each other resulting in breakage.

A still further object of the invention is theprovision of a machine of this character, which is simple in its construction, thoroughly reliable and emcient in operation, sanitary, and inexpensive to manufacture.

With these and other objects in view, the

invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which disclose the preferred and modified forms of embodiment of the invention and pointed out inthe claims hereunto appended.

Beferringto the drawingsin detail. particularly Figures 1 to 5 inclusive, the washing ma- 15 user of the machine.

chine comprises a stationary casing in tl'ilS instance of substantially square shape in contour although it may beof any other desirable shape and'is supported-through the medium of 5 legs, a portion of each being-indicated at II.

This casing constitutes a tank having a suitable water-tight cover l2 at the open top thereof and such cover is mounted so that it can be opened or closed for giving access to the interior of the 10 tank. At the bottom of the tank Ill centrally thereof is a well i3 into which leads a water supply pipe M having a hand controlled valve for regulating the supply of water and for the cutting off of such supply at the will of the trolled cut-off valve ll so that the machine can be drained at the will of the user thereof. This well opens upwardly into the tank constituted 2 by the casing Ill.

Centrally projected through the well I3 is a solid rotatable coupling shaft I8 mounted in bearings l9 and having at its lower end connection with a driving shaft of an electric motor 2| stationarily supported in any suitable manner.

The shaft l8 works in a stufil ng box 22 carried by the well I3 at its bottom while carried. up.- wardly within the tank i0 is a hollow rotatable shaft 23 which at the lower solid stud end 24 has coupling with the shaft II. The shaft 23 longitudinally thereof is provided in the upper portion of the same with lateral outlet ports 24' for water rising vertically therein and admitted through inlet slots 25 provided in the lower portion of said shaft 23 close to the end 24 thereof.

The shafts l8 and 23 rotate with the driving shaft 20 of the motor 2| when active. 1

Fixed to the shaft l3 below the slots 25 in the shaft 23 is a radially bladed water-wheel 23, thelatter operating in a circular stationary water trough or pan 21 within the well l3 and elevated from its bottom by 'legs or separated vertically disposed webs 23, the trough or pan 21 concen- 5 trically about the shaft l8 being formed wlt h'a circular opening 29 in its bottom and of considerably greater diameter than the cross sectional diameter of the said shaft l8.

' Capping the pan or trough 2I is'a conical shaped internally finned hood or water ejector nozzle 30 truncated at II which is the discharge mouth of said nozzle or hood, the fins being denoted at 32 and radially disposed within said hood or nozzle.

Above the hood or nozzle :6 and suitably fixed Leading from the well lit is a -drain pipe l6 equipped with a hand coning purposes.

to the shaft 23 is an inverted conical shaped spreader 33 dished at 34 while exteriorly of this spreader are radially disposed wings 35, these drical container for wiper brush action thereon being cut away at 3B for overriding the hood or the hollow shaft 23 and flood the sponge head or brush. The required quantity of water can be let into the casing and the levelof the water within is preferably at a plane immediately below the lowermost edges of the wings 35, this being thenormal water level. That is to say, this water level just mentioned has to do with the at its interior. Tapped on the upper end of the shaft 23 is a'disk-like spreader head 39 which is removable and this head is preferably made from rubber stock, and which spreads the water as it passes from the upper end of the hollow shaft 23.

Concentric to the legs or webs 28 beneath the trough or pan 2! is a wire mesh annular screen 43 while extending upwardly from the bottom of thewell [3, through the same and into the casing ID are electric heating posts or tubes 44, these being controlled from a hand switch 45, the motor 2| being of the reversible type and being controlled from a reversing switch 46 which switches 45 and 46 are accessible to the user of the machine.

Removably fitted within the casing is a twosection article carrying cage or tray, the sections thereof being independent of each other and denoted at 41 and 48, respectively, one being adaptable for articles to be washed, such as pots, pans or the like (not shown) and the other section in its equipment carrying stationary holding racks 48 and 50, respectively, these serving to hold dishes or other like articles (not shown). The section 41 preferably carries the racks 49 and 50 and at corners thereof is equipped with pockets 5| receptive of silverware such as knives, forks and similar miscellaneous articles (not shown). The sections 41 and 48 are provided construction as shown in Figure 1 while in Fig ure 9 of the drawings the normal water level is in the plane with the upper open end of the well 55. I

What is claimed is:

1. A machine of the character described comprising a casing having a well at its bottom, a

hollow shaft rotatable in said casing and having outlet openings, 2. fluid supply nozzle stationarily held operatively associated with the Well and delivering fluid into the casing and said shaft, a bladed fluid wheel fixed to the shaft and interiorly of said nozzle, a fluid supply pipe opening for communication with the well and nozzle, a drain pipe leading from said well, fins fixed interiorly of said nozzle, aspreader carried by said shaft above said nozzle, and wings projecting radially from the spreaker and overhanging said nozzle.

2. A machine of the character described comprising a casing having a we at its bottom, a hollow shaft rotatable in sai casing and having outlet openings, a fluid supply nozzle stationarily held within the well and delivering fluid into the casing and said shaft, 21. bladed fluid wheel fixed to the-shaft and interiorly of said with feet 52 elevating the same slightly from the bottom of the tank or casing ll), these sections being independent of each other and cut away at 53 to afford clearances for the posts or tubes 44 and other'centrally assembled equipment of the machine projected within the said tank or casing. The vertical side walls of the sections 41 ind 48 are created with openings 54 for effecting hand holds convenient for the lifting of the sections or the lowering of the same in the use thereof with the machine.

With reference to Figure 1 of the drawings, it will be noted that the water through the supply pipe l4, which is hot, will flow from the well l3 under the force of the water wheel 26 through the pan or trough 27 upwardly through the nozzle or hood 30 and be spread by the spreader 33 angularly between the wings 35 toward the side of the tank or casing 18, a portion of the water admitted being carried upwardly through the casing 23 and discharged through the outlet ports 24' therein. The wings 35 and the paddle function to agitate the water sent into the tank or casing 10 and thus the contents of the sections 4'! and 48 will be washed in the operation of the machine. The soiled ordirty water is drawn off through the drain IT, the screen 43 being adapted to function for eliminating circulation of solids in the washing process through the activity of the machine. The tubes or posts 44 may serve to further heat the water "or when the water is drained off from the tank or casing ID for dry- These outlet ports 24' are laterally disposed.
